The present case was a partially edentulous patient whom we comprehensively treated with a wide-area jawbone support device that became covered by the health insurance system in 2012, orthodontic devices and bone augmentation. Five years and six months have passed since the superstructure was first attached. The patient was a 32-year-old female who visited our department in June 2016 seeking treatment for her masticatory disorder caused by movement of her mandibular anterior teeth. Although she had no past medical history, her family history revealed that her sister had congenital partial oligodontia. She had 18 missing teeth in the jaw and midline diastasis of the maxillary anterior teeth. Under general anesthesia, maxillary and maxillary deciduous teeth were extracted, and bone augmentation by autogenous bone grafting of maximally anterior teeth (collected from bilateral mandibular protuberance) was performed. We implanted nine fixtures (Nobel Active, Nobel Biocare, Göteborg, Sweden, Φ4.3×10 mm in 14 parts, Φ3.5×13 mm in 13 parts, Φ4.3×13 mm in 12 parts, Φ3.5×11.5 mm in 22 parts, Φ3.5×13 mm in 23 parts, Φ3.5×10 mm in 32 parts, Φ5×13 mm in 35 parts, Φ3.5×10 mm in 42 parts, and Φ5×13 mm in 45 parts, a total of 9 implants). A provisional bridge was attached in February 2017, 7 months after the operation, and the final superstructure was attached in November 2017. It has been 5 years and 6 months since the final superstructure was installed, and the patient is doing well.
